Say: What beautiful names!
Think: I love the name Astrid but would only use it as a middle name because of any nicknames that could come from it. I always saw Linden as a boys name and with Astrid seeming like a really princessy name, its a bit odd that her twin has a much more masculine name.

Say: HiRamona and Issac! It's nice to meet you.
Think: Ramona feels clunky to me (it's the "mona" part I dislike); it's not my style. Isaac is a great name, though. Not sure I'm crazy about the two names together as a sibset.
